Bet that bass is fantastic! I am "shy" of the 5998's now - with 2 reports of blown headphones....

Good NOS 5998 are the last of the Mohicans now. That is true of all the classic power tubes such as the GEC 6as7g. Stay away from old used 5998. That applies to any tubes.

It's good to have a wide range of tubes. You get to vary your tones. Now running Siemens c3gs and 5998. It's an eye opener. Dynamics, clarity with a hint of warmth and deep bass.

Question for Glenn:

Kosher to use a single pair of 6080 and a single pair of 6BX7's as output tubes in the GOTL?

And another question for Glenn: Is it safe to leave only a driver tube with the amp turned on (without any power tubes) to let it burn in? I am a little paranoid of new tubes after ruining one of the drivers in my T1 headphones. I found that most old tubes resent being woken up after of decades of sleep and protest with all kinds of sounds. Usually these sounds disappear, but when they don't and sound like loud pops or explosions your headphones could be at risk.....
Is it possible that headphones are more sensitive than speakers?

One 6080 per side fine the are similar to a 6AS7
One 6BL/BX7 not so much use at least two or it will be over current.

Running just the driver is fine no problem but most bad things happen with the output tubes arc over.

Meant one 6080 plus one 6BX7 per side....

I am sure that Glenn will correct me if I am wrong. It probably won't hurt anything. However, you need to remember that the 6BX7 has an amplification factor of "10", whereas the 6080 has an amplification factor of "2". Very frankly, mixing output tubes with different amplification factors doesn't seem to be a good idea. But again, I doubt that it would hurt anything.....

That will be OK Don't know how it will sound though.

How does it sound ? What tubes are you using?
I used a 13D1 and six 6BX7s driving the Auteur to test sounded wonderful.

Sounds fantastic right off the bat with the 5998s and TS 12SL7. Since I'm in the middle of packing up our place I reached for the easiest to get power tubes. Tomorrow I'll be digging through the box for the 6BX7s and pairing it with the 13D1.

The biggest take away from the amp is the layers. So many different layers in songs I knew were there but were never separated like this. Thanks for working hard on the amp Glenn!

Looks exactly like my amp. Congrats.

TS 12SL7gt bgrp with 5998 or 6 x 6bx7gt sounds incredible. You could practically stop tube rolling there but in the interest of this hobby, you must discover more for yourself.
